A tooltip, aka infotip or hint, is a small box of text
that appears when a user hovers the mouse pointer over an item, such as a
particular word or phrase, on a webpage. If you wish to display a
tooltip when a user hovers the mouse pointer over text on a webpage,
there are a number of ways you can do so. The simplest way to do so
is to specify a title attribute, which is an
HTML global attribute with the
span tag. E.g.:

<span title="This is the tooltip text to be displayed when the mouse is
hovered over the spanned text.">example text</span>

Books and other documents may often include pages intentionally left blank
stating "This page [is] intentionally left blank." As explained in the Wikipedia
intentionally blank page article, this is often done due to the way
pages are printed from a much larger sheet of paper or for legal reasons.
On the web you can find an online equivalent in
The This Page Intentionally Left Blank (TPILB) Project which notes:

In former times printed manuals had some blank pages, usually with
the remark “this page intentionally left blank”. In most cases there
had been technical reasons for that. Today almost all blank pages disappeared
and if some still exist here and there, they present flatterly comments
like “for your notes” instead of the real truth: This page
intentionally left blank!

Nowadays the “This Page Intentionally Left Blank”-Project
(TPILB-Project) tries to introduce these blank pages to the
Web again. One reason is to keep alive the remembrance of these famous
historical blank pages. But it is the primary reason to offer internet
wanderers a place of quietness and simplicity on the overcrowded World
Wide Web—a blank page for relaxing the restless mind.

Since I sometimes want to take browser screenshots that display
options that are available in various browsers, but would prefer not to
have any webpage content displayed in those screenshots, I've also created a
this page intentionally
left blank" page.

Put chrome://settings/siteData in the Chrome address bar
where you normally place URLs which will show you a list of all the cookies stored
on the system.

In the "Search cookies" field, type the relevant domain name, e.g.,
mattel.com; you will then see only the cookies for that particular domain.

Click on "REMOVE ALL SHOWN" to remove all of the cookies for the domain. You
will then be warned "This will delete any data stored on your device for all
the sites shown. Do you want to continue?" Click on the "CLEAR ALL" button
to delete all of the cookies for the domain.

You can also go directly to the list of all the cookies associated with
a particular domain by putting chrome://settings/cookies/detail?site=
followed by the domain name in the address bar, e.g.,
chrome://settings/cookies/detail?site=mattel.com.
You can then click on "REMOVE ALL" to delete all of the listed cookies for
the domain.

If you wish to use the Chromium browser on a
CentOS
Linux system, you can install it by running the command
yum install chromium from the root account. You can check if
it is already installed on a CentOS system with rpm -qi chromium.

When you start the Firefox
web browser, it will attempt to determine if the network connection available
to it when it starts is via a
captive portal.
If you use a hotel's Wi-Fi service, a free WiFi service provided by a
restaurant or other business, or some other public WiFi service, when you first
open your browser you may see a web page asking you to accede to terms of
service, an
acceptable use policy, or to provide some authentication
information, e.g., perhaps your name and room number for a hotel,
or to provide payment information if you are accessing a wireless
service that is not free. You won't be able to go elsewhere on the
web, at least not easily, until you deal with the demands/conditions
specified on the captive portal page.

Sometimes I encounter difficulties signing out of an account on Amazon's
website when I need to sign into another account, if the resolution of the
display isn't great enough to allow me to see the bottom of Amazon's list of
choices where the sign out option appears.
If I need to logon on such a system, there's no problem. If I visit
Amazon's home page, I can click on "Hello. Sign in Accounts & Lists" where
I see a "Sign in" button.

So only the root account had write access to the file. I then checked to
see which account elogd was running under. The program lisens on port 8080
on that system. If you don't know the port that is being used for ELOG, you
can find it in the /etc/elogd.cfg file. E.g.:
